Description

The dlpi_enabmulti() function enables reception of messages destined to the multicast address
pointed to by addrp on the DLPI link instance associated with DLPI
handle dh. The DLPI link instance will pass up only those messages destined
for enabled multicast addresses. This operation can be performed in any DLPI
state of a handle.

The dlpi_disabmulti() function disables a specified multicast address pointed to by addrp
on the DLPI link instance associated with DLPI handle dh. This operation
can be performed in any DLPI state of a handle.

Return Values

Upon success, DLPI_SUCCESS is returned. If DL_SYSERR is returned, errno contains the
specific UNIX system error value. Otherwise, a DLPI error value defined in
<sys/dlpi.h> or DLPI_EINHANDLE is returned.
